HUSKING APPARATUS.

Specification of Letters Patent.

Patented June 4, 1918.

Application filed September 10, 1917. Serial No. 190,521.

To all whom it may concern Be it known that 1, WILLIAM J. OSBORNE, a citizen of the United States, residing at Walla Walla, in the county of Walla l valla and State of Washington, have invented cer tain new and useful Improvements in Husking Apparatus, of which the following is a specification.

This invention relates to husking devices, and more particularly a device of this kind in the nature of an attachment for re-elean crs, fanning mills and other grain cleaningor separating apparatus.

.As a fanning mill or similar grain cleaning apparatus cannot remove the husks which may still be carried by the grain, the present invention has been devised to efieet a thorough removal of such husks, and to this end the invention consists in a novel combination and arrangement of parts to be hereinafter described and claimed.

In order that theinvention may be better understood, reference is had to the accompanying drawings forming a part of this specification, and in said drawings- Figure 1 is a cross section of a fragment of a grain cleaning apparatus, showing the application of the invention thereto; Fig. 2 is a plan view thereof; Fig. is an enlarged cross section of the apparatus, and Fig. 4 is a plan view thereof, with parts broken away.

Referring specifically to the drawings, 10 denotes a fragment of the casing of a grain cleaning apparatus, the same containing the usual screen 11 and a fan 12. The grain inlet to the casing 10 is through a hopper com.- prising a body 13 mounted over atop opening in the casing, and containing the usual inclined slides 14 which are spaced at their lower edges for the passage of the grain into the casing. The husking attachment is mounted in the hopper body, beneath the slides 14, and it is composed of the following parts-:

In the hopper body 13 are mounted two spaced plates 15 and 16, respectively, extending between the ends thereof and held in a frame 17 secured by bolts 18 to the end walls of the hopper body. The plate 15 has a roughened or corrugated facing 19 of any suitable material, and the plate 16 has a similar facing 20.

The plate 15 has a rectilinear reciprocatory motion and the plate 16 is stationary. Thus the partially cleaned grain is rubbed by the plate 15 against the plate 16 and the husks are completely removed by this rubbing action.

The plate 15 is actuated by a pitinan 21 driven by a wrist wheel 22 obtaining power from any suitable source.

The facing 19 of the plate 15 is continued above the top edge of the latter and curved rearward as shown at 23 to fit under an apron 24 positioi-ied beneath one of the slides 14, whereby the grain is prevented from getting behind the plate. At the top of the plate 16 the facing 20 is bent rearward .at an angle, as shown at 25, to correspond to the slope of the other slide 14, beneath which latter it extends. so that the grain is prevented from getting past the husker even though the slide is opened wider than necessary. This. angle guard piece may be integral with the facing or made separate therefrom. Both ends of the facing 19 are left free of corrugations, as shown at 26, so that it may have a smooth bearing where it engages the frame 17, the two bearing surfaces being held in contact by vertical rollers 27 mounted in springebacked bearings 28 carried by the frame 17, said bearings allowing the plate 15 to yield rearwardly to a certain extent. The bottom of the plate 15 rests on flanged rollers 29 carried by the frame 17.

To the upper part of the plate 15 are fastened upstanding fingers 30 which project into the space between the slides 14 and as they move with the plate, they act as stirrers to continually agitate the grain and prevent congestion.

On the back of the plate 16. at each end thereof, are fastened castings '31 which serve as bearing plates for set screws 32, and projecting from these castings and integral therewith, are hooks 33. The ends of the,

plate 16 fit snugly against wings 34 extending rearward from the frame 17 to prevent grain from getting past. The wings 34 are grooved, as shown at 35, to carry sliding members 36 having lugs 37 through which the set screws 32 are threaded. The wings are also provided with outstanding pins 38 engageable by the hooks 33. As the set screws 32 engage the casting 31 above and below the hooks 33, the correct angle of in clination of the plate 16 can be readily obtained, and the plate securely held at the desired angle, the hooks providing a pivotal connection between the plate 16 and the slides 36. Upon loosening the set screws 82, the plate 16 can be readily removed for repairs.

Each sliding member 86 is yieldingly held in place by a spring 39 coiled around a shaft 40 between lugs 41 and 42, the former being on the member 36 and the latter on the wing 34. Against the lug 42 seats a Washer 43 held on the shaft 40 by a cotter pin 44, by which the shaft is held against any forward movement but is yieldable rearward against any sudden pressure against the plate 16 which might be caused by any foreign substances entering between said plate and the plate 15.

The shaft 40 is threaded through the lug 41 but passes loosely through the lug 42, and hence it will be evident that by turning the shaft the spacing of the plates 15 and 16 may be regulated.

Both ends of the plate '16 are supported in the manner hereinbefore described, and the shafts 4C0 pass through the wall of the hopper body 13, on the outside of which latter they are connected by a sprocket-andchain, or other suitable gearing 4:5 for simultaneous operation.

The plate 15 can be withdrawn for repairs through an opening in the wall of the hopper body 13 through which the pitman 21 passes.

I claim: 1

1. A husking mechanism comprising resiliently yielding and reciprocatory plates which are spaced and have their opposite surfaces roughened, means for operating the reciprocatory plate, feeding means discharging between the plates, supports for the resiliently yielding plate having outstanding wings between which said plate seats, slides to which the plate is pivotally connected, said slides being carried by the wings, ad-

justing screws carried by the slides and en siliently yielding and reciprocatory plates which are spaced and have their opposite surfaces roughened, means for operating the reciprocatory plate, feeding means discharging between the plates, supports for the resilientlyyielding plate having outstanding wings between which said plate seats, slides carried by the wings, a detachable connection between the slides and the plate, and screw shafts carried by the wings and having a threaded engagement with the slides.

8. A husking mechanism comprising resiliently yielding and reciprocatory plates which are spaced and have their opposite surfaces roughened means for operating the reciprocatory plate, feeding means discharging between the plates, supports for theresiliently yielding plate having outstanding wings between which said plate seats, slides carried by the wings, a detachable connection between the slides and the plate, andholding means carried by the wings and engageable with the slides and adjustable for carrying the plate toward and from the reciprocatory plate.

4:. A huskingmechanism comprising resiliently yielding and reciprocatory plates which are spaced and have their opposite surfaces roughened, means for operating the reciprocatory plate, feeding means discharging between the plates, supports for the resiliently yielding plate having outstanding wings between which said plate seats, slides to which the plate is pivotally connected,

, said slides being carried by the wings, ad-

justing screws carried by the slides and engaging the plate on opposite sides of the pivot, and holding means carried by the wings and engageable with the slides and adjustable for carrying the plate toward and from the reciprocatory plate.

5. A husking mechanism comprising resiliently yielding and reciprocatory plates which are spaced and have their opposite surfaces roughened, means for operating the reciprocatory plate, feeding means discharging between the plates, supports for the re siliently yielding plate having outstanding wings between which the plate seats, slides extending from the plate and carried by the wings, and screw shafts yieldingly connected to the wings and having a threaded engagement with the slides.

In testimony whereof I afiix my signature.
